'Be it known that I, CHARLES T. RIPGELY, a citizen of the United States,residing at Springfield, in the county of Clark and` Statebf Ohio, haveinvented certain new and useful Improvements .in Demountable- Wheels forVehicles, of which the following isa specification, reference being hadtherein to the accompanying drawing. i This' invention relates todemountable l wheels for automobiles and vehicles in gen- Ijig. 2 is asectional' view' on the line 2--2 of, Fig. 3; Fig. 3 is a' sectionalviewon the line eral.

and described in my co-pending applications, SenNos. 3254 and 50,327,filed June 7, 1915, and Sept. 13, 19 15, respectively.

The object of this invention is to provide v `an organizationv of* partswhereby a Wheel In the accompanying drawings, Figure 1 is a sectionalview on 'the line 1-/-1 of Fig. 3,

the parts being shown in locked position;

3 3 of Fig. l; Figa is a sectional view similar to Fig. 3 but showingthe parts in unlocked position; Fig. 5 is a sectional view on theline5-5 of Fig. 1; and Fig. 6 is a detail perspective ofthe operating'lever.

In the embodiment ,of the invention here shown the usual axle lhasmounted thereon a main hubk 2. This main hub, vas shown,

has the inner portion thereof enlarged in order that the hereinafterdescribed supplemental hub can be easily removedtherefrom Withoutinterfering with `the main hub. This arrangement has the furtheradvantage of being able to properly locate the means for keyingthesupplemental hub upon the main hub. Thehub 2 is providedWithantifriction bearings 3 andhas screw-threaded upon its outer vend asuitable grease cap 4.

`The hub 2 is provided near its inner end 4 with a radial flange 5against which the supplemental hub is adapted to lie. 4Thesupplemental-hub, as indicated at'6, comprises a sleeve which encirclesthe raised portion of the hub 2 and at its outer end has a radial a'ngeor face plate 7. `An annularplate 8 is located upon the rear qend of thesleeve portion` of the supplemental hub 6. The spokes of'the device hereshown consist of ai The present invention is in the naturel Y of' animprovement upon the devices shown DEMOUNTABLE VII-1121313l FORVEHICLES;

series ofl metal `cz'1sin gfs,fas indicated at l0,

having wood llers, asindicatedat 9. v These spokesar'e adapted-to besecurely clamped spoke, however, may be used, but it -'will. be seenthat by this method of clamping the 'same to the lsupplemental hub avery rigidstructure is insuredls 'I' `-`prder to key v'the supplementalhub to l'liv main hub the main specification of Letters Patent. PataetdJune .13 1916-.

Application and December 27, '1915. serial No. 68,653.

hub'is provided at itsraised portion with recessesvl2 extending"longitudinally, of the hub and arranged circumferentiallyl therearoundvin spaced v'apart relation.` Within each of these recesses -isanlelongated bar. of

metal 13 which extends above the plane of the surface of said main hub.These bars are suitably fastened to the hub by means of screws 14. Thesupplementaljhub'has .a corresponding series of slots 15 adapted'toregister with the projecting portions of the bars 13 It will be s eenthat by this arrangement the supplem 'tal hub can be attached to themainhii by registering the slots therein with the metallic bars of themain hub and then'slidin'g the same axially against the flange 5. Thisarrangement insuresv the rotation of the supplemental hub .with themainhub4 and provides a rigid structure which isnot easily damaged.

In order to lock the supplemental hub against axial movementrelativetothemain hub I have provided a lockingmember 16. v

This locking member comprises a .sleeve 17 encircling the reducedportionof the' hub 2 and having a radial iange 18;'at; its inner end.This radial iange extends vertically and lies closelyadjacent to .thesupplemental hub Gand its iange 7. In order to securely fasten thelocking member to the supplemental hub I 4have provided the former-.witha recess 19 adapted to enga-ge 7 by means of series of screws 21. Bythis arrangement it will be seen that the locking an annulanplate 20fastened to the flange right angles to the 'axis thereof andare spacedapart, as clearly shown in the drawings, thespaces being indicatedat24:.v Projecting inwardly at the inner end ofl the .locking member 16 isa sriesot1 circumferentially arranged lugs 25 located to the rear of thelugs 2-3 and paralleltherewith. The

lugs 25 are'spaced apart, the spaces being indicated generally at 26andgare arranged ber'16 is screw-threaded, as 'indicated at 27,' and hasscrewed thereon a dust cap 28. In

`to coperate with the lugs upon the ina-in hub 2, as vwill b e describedhereafter. -The outer end of the sleeve of `the locking inem# order/tovlimit the amount of rotation of the said locking member 16 stops are piovided. lIn the present embodiment of the invention the locking member isprovided with a curved groove-or recess, as shown at 29. The wallsl of'the extremities of this recess constitute stops and are indicated byl/thenumerals 30 and 31. Fixedly mounted upon the supplementalhub andextending into the said groove 29A is 'a lug` 32. By this arrangement itwill be seen that the rotation Yof the .locking member is limited by thelength of the groove, the lug 32 engaging either one end or the other'of the said groove as the locking member is rotated.

Inorderto prevent thev displacement of the locking "iiember wheiin thefwheel is in use` the supplemental hub i's providedl with a casing 33 inwhich is mounted a spring 34: which, when :the parts are in lockingposition, presses a detent 35 into engagement with la hole 36 located inthe locking inember'16. It will be seen by this arrangement that beforethe locking member can be operated the detent must be pressed out of4.engagement with the hole 36. In front of the detent is located a plate37 which acts as a protector to prevent the accumulation of dust withinthe casing, thereby interfer- .ing-with the operation of they detent.The

plate 37 is loosely mounted within the slot `36 and can slidelongitudinally thereof.

' shown at 43, and the inner end of the curved 'portion has a projectinglug, as shown at 7 44. In using this lever the -lug 4t is placed throughthe aperture 40, thereby engaging the plate 37 and pushing the detent 35out of the hole 36. vThe hook portion-L3 is adapted to engage the lug45, as shown in Fig. 3. .When the lever is thus `located an upward sniopveinent of the handle thereof will rotate the locking member 16.from locked to4 un locked position.

As vshown in Figs. 1 and 3, thevdev'iceis .in locked position. It willbe seen that the lugsk 25 of thelocking member are located centi'allyand tothe rea-r of the lugs 2,3. WhenI in this position it is impossibleto move the supplementalhub axially. It will alsobe noticedl that inthis position the lug 32 engages the end 31 of the groove 29. It is,therefore, apparent that whenV the member l16 is rotated from unlockedto locked position this stop willy prevent the further rotation thereofafter the same is locked. When it is desired to remount the wheel, the:lever is attached to the locking member, as described above, -and thesame is rotated. This rotation can continue until the lug 32 engageswith the end 30 of the groove. lVlien in this positioirtlie wheel can bemoved axially. The lugs 25 of the; locking member will then be locatedin front of the spaces 24 between the lugs 23 ofthe hub 2. Thus, it willbe seen thatl the sup-- .plemental hub Acan-be moved axially withoutinterference, the lugs 23 being in aline- In the constructionl of thedevice the ment with the spaces 26 between the lugs 25.

longitudinal bars 13Y are located upon the,-

niainhub `2 to` the rear and between each two successive lugs By. Lthis/arrange- 'ment when the lugs 25 are in line with the spaces 24 and thelugs 23 are in line with the spaces 26,1 the supplemental hub can thenbe easily vmoved axially to deniount the same.

It will be seen that I have provided a. del vice .which is simple in allof its parts, rigid and easily operated. The `action is positive. andthe parts so coperate as to Vlimit the movement of the locking member atthe proper position` either to lock or unlock the same. Movable par-tshave been eliminated? asfar as possible and the structure 'of theelements is such that they can be manufactured at a low cost.

IVliile I have'shown and described one embodiment of my ,invention itwill be undeistood that this has been chosen for the purposes ofillustration only, and that I do not desire to be limited to the detailsof construction shown and described, for obvious modifications willoccur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent. is
